When you are listing a new product for the first time SellerExpress doesn’t know how much you’re going to charge for postage. This is because Amazon applies the postage once your product has been listed.
What does this mean for your product listings? Well when you upload your product for the first time we will put your product up as either you’re Default Sale Price or AUK Price (if you applied one). Once your repricer runs for the first time you’re price will be updated to take postage into account.
If it looks like this is happening to your product and it’s been up for a while click Why This Price to see why it is priced the way it is.
